Summary It has been generally hypothesized that habituation mediates the effects of pheromone‐based disruption strategies used in the management of moth pests. The current study demonstrates that pheromone‐mediated sexual response in the tobacco budworm moth, Heliothis virescens (F.) (Lepidoptera: Noctuidae), can in fact be modulated by conditions consistent with the production of habituation. An ethogram was used to measure response strength in a wind tunnel experiment where male moths were allowed to respond freely to one of two different blends of female pheromone in 16 trials over 4 days. Post‐test measures were collected to investigate stimulus specificity and long‐term effects. In conditions appropriate to the formation of habituation, habituation will develop and disrupt male sexual response to female sex pheromone. Males repeatedly exposed to plumes of synthetic pheromone blends display a habituated response lasting up to 96 h. Habituation rate and spontaneous recovery of response strength are greater with less intense stimuli. Additionally, males habituated to one blend express no habituation of sexual response when exposed to a different blend. This indicates a high degree of stimulus specificity, which could facilitate outbreeding, and that moths attend to the configuration of the pheromone blend, not simply to its elements.

“…Dioryctria amatella. Using the paired design of Hendricks et al (1982), we applied the mating-disruption treatment to both plots and continued to alternate it with the control at 2-to 3-d intervals from 10 September to 29 October 1984. A rate of 2.5 g/ha of Z-11-16:Ac was used during mating-disruption periods.…”

SYNTHETIC PHEROMONES DISRUPT MALE DIORYCTRIA SPP. MOTHS IN A LOBLOLLY PINE SEED ORCHARD

et al. 2000

Synthetic sex pheromones released in a loblolly pine, Pinus taeda L. (Pinaceae), seed orchard interfered with the ability of male coneworm moths, Dioryctria Zeller spp. (Lepidoptera: Pyralidae), to locate traps baited with sex pheromones or live females. Pherocon 1C® traps baited with synthetic pheromones or live conspecific females were hung near the center of two 1.2-ha circular plots during emergence of Dioryctria amatella (Hulst), Dioryctria disclusa (Heinrich), and Dioryctria merkeli (Mutuura and Munroe). In a paired design, trap catches for the mating-disruption treatment with synthetic pheromone dispensers consisting of three polyvinyl chloride rods placed in every tree were compared with the control treatment. Treatments were alternated at intervals of 2–3 d. Trap catches of D. amatella were reduced by 91% when plots were treated with 2.5 g/ha of Z-11-hexadencenyl acetate. Catches were reduced by 99.5% for D. disclusa and by 97% for D. merkeli when plots were treated with 12.5 g/ha of Z-9-tetradecenyl acetate, whereas catches of D. amatella were unaffected by this mating-disruption treatment. Daily disappearance of Z-9-tetradecenyl acetate from the dispensers averaged 0.46 g/ha or less. Manually placing dispensers on nylon lines in the tops of trees was an effective method for releasing synthetic Dioryctria pheromones in the orchard. These data suggest it may be feasible to prevent mating of Dioryctria spp. in pine seed orchards by using synthetic pheromones for mating disruption, but large-scale tests will be required to demonstrate cone protection.

“…Sex pheromones of insect species usually consist of multiple components. The behavioural role of various pheromone components has been studied in detail for a number of species (for examples, see Baker & Card6, 1979;Hendricks et al, 1982;Linn & Roelofs, 1983;Grant et al, 1988). It has also been convincingly shown that male moths initiate upwind flight in significantly higher proportions in response to the complete blend of components, compared to single components or a partial blend (Linnet al, 1986).…”

Attraction of male Agrotis segetum Dennis & Schiffermüller (Lepidoptera: Noctuidae) to sex pheromone traps in fields, which were treated with one or three pheromone components was investigated. Small plots of 1/4 ha size were treated with synthetic pheromone, released by 25 evenly dispersed latex rubber tube dispensers. The dispensers were loaded with either 500 μg Z5‐10:OAc (50 mg/ha), or 1000 μg Z7‐12:OAc (100 mg/ha), or a 3‐component mixture consisting of 500 μg Z5‐10:OAc + 1000 μg Z7‐12:OAc + 1000 μg Z9‐14:OAc. Pheromone traps were placed both within and outside of the treated area in a cross design, with an intertrap spacing of 15 m. Release rates from disruption dispensers were measured in the laboratory after being exposed in the field. The release rates of the components were estimated to be 0.44, 0.11, and 0.06 μg/h/dispenser for Z5‐10:OAc, Z7‐12:OAc and Z9‐14:OAc, respectively. The highest effect of disruption was achieved by the three‐component blend, resulting in a significant suppression of trap catches extending 5 m outside of the treated area. The Z5‐10:OAc treatment resulted in reduced trap catches inside the treated area, but the effect did not extend outside. Z7‐12:OAc alone did not result in any significant reduction in trap catch. The results indicate that different mechanisms may explain the disruptive effect of the treatments and that the single pheromone components are not as effective as the three‐component blend.
